Detailed Implementation

[0022] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0023] refer to Figures 1 to 5

[0024] A dustproof mechanism for the outlet of an optical film cutting machine includes a conveyor table 2 and an output conveyor belt 3 located behind the outlet of the cutting machine 1. From front to back, the conveyor table is equipped with a waste material drive roller 4, a waste material reversing roller 5, and a waste material winding mechanism 6 located above the reversing roller. This allows the cut waste material to be driven by the waste material drive roller and guided into the waste material winding mechanism for collection via the reversing roller. A clamping roller assembly 7 is located between the conveyor table and the output conveyor belt to clamp the optical film backward. A baffle 8 is located above the front of the output conveyor belt. The baffle has a telescopic plate 9 that can slide forward to above the waste material reversing roller. The telescopic plate moves backward between the waste material reversing roller and the waste material winding mechanism, thereby collecting dust and debris falling during normal waste material winding by blocking the flow. The telescopic plate can also move forward when a certain amount of waste material needs to be unloaded or when the winding roller needs to be installed.

[0025] In this embodiment, the waste material driving roller includes a roller shaft 41 longitudinally arranged above the conveyor table. Both ends of the roller shaft are rotatably connected to the conveyor table via brackets 42. A pair of rubber rollers 43 are mounted on the roller shaft to press down on the sides of the waste material. A first motor 45, which drives the roller shaft to rotate via a reducer 44, is mounted on the bracket. The reducer is an angle reducer. Thus, the pair of rubber rollers press down on both sides of the waste material, driving the waste material out.

[0026] In this embodiment, to better drive the cut optical film forward, drive rollers 21 are rotatably connected to the front and rear ends of the conveyor table, and a transparent conveyor belt 22 with its work station section located on the conveyor table is placed between the pair of drive rollers. Thus, while the waste material driving pressure roller and the reversing roller waste material winding mechanism drive the waste material to wind up, the cut optical film is conveyed backward by the transparent conveyor belt.

[0027] In this embodiment, the waste material winding mechanism includes a mounting frame 61. A detachable winding roller 63, driven by a second motor 62, is longitudinally mounted on the upper end of the mounting frame. A swing frame 64 is hinged to the side wall on the discharge side of the cutting machine, and a tension roller 65 is rotatably connected to the swing frame. After the waste material passes over the reversing roller, it passes over the tension roller and is then fed into the winding roller for winding. The tension of the waste material during winding is achieved by the gravity of the tension roller.

[0028] In this embodiment, the mounting frame consists of a first frame 611 and a second frame 612. The second motor is mounted on the upper part of the first frame and connected to a reducer. A connecting bushing 66 is mounted on the output end of the reducer. The inner ring of the connecting bushing is polygonal. One end of the take-up roller is polygonal and is inserted into the connecting bushing. The other end of the take-up roller has a rotating part 631 for supporting the upper end of the second frame. After the take-up roller is inserted into the connecting bushing, it is supported on the upper end of the second bracket. The upper end of the second bracket has a recess for the rotating part to be inserted into, so as to position the rotating part. The insertion and engagement of the take-up roller and the connecting bushing facilitates the assembly and disassembly of the take-up roller.

[0029] In this embodiment, the two sides of the shield are connected to the frame of the output conveyor belt via fixing brackets 81. Transverse guide rails 82 are installed on both sides of the upper surface of the shield. A pair of sliders 91 are provided on both sides of the rear of the telescopic plate, cooperating with the corresponding transverse guide rails, to allow the telescopic plate to slide laterally. The telescopic plate can be made of lightweight materials such as plastic sheets or thin metal sheets, so its suspension at the front end is not affected.

[0030] In this embodiment, in order to automatically drive the telescopic plate to move, a transverse lead screw 84 driven by a third motor 83 is rotatably connected to the upper surface of the cover plate, and a nut seat 92 that cooperates with the transverse lead screw is fixed to the lower rear side of the telescopic plate.

[0031] In this embodiment, the pinch roller assembly may consist of a pair of longitudinally arranged and vertically positioned rubber rollers, with one end of the two rubber rollers meshing through a gear pair, and one of the rubber rollers being driven by a motor. The surface of each rubber roller is provided with a replaceable adhesive layer to adhere dust or other particles from the optical film. The pinch roller assembly may also be a conventional pinch roller.

[0032] In this embodiment, in order to better transport the optical film backward, the output conveyor belt is composed of several spaced strip-shaped transmission belts 31.

[0033] In this embodiment, an ion fan 10 and an ion bar 11 are sequentially mounted above the rear of the output conveyor belt along the conveying direction to remove static electricity from the optical film. The ion fan has multiple blades arranged longitudinally. The ion fan can be a suspended ion fan, such as the KRB-205 model. The ion bar can also be a commercially available ion bar.

[0034] If the terms "first" and "second" are used in the above description to define the components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of distinguishing the components in the description. Unless otherwise stated, the above terms have no special meaning.

[0035] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0036] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0037] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0038] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
